I have 1.7 version of golang and I want to update golang to 1.8 from command prompt. Uninstalling and Installing it again is always an option, but can I update it using commands on Windows 8.1?
I think that GVM could be a good option for that. GVM is an interface to manage Go versions in your computer. It allows you to change the Go version and even installing/uninstalling different golang versions by command prompt.
You can install a new version by typing:
gvm install go1.4 -B gvm use go1.4 export GOROOT_BOOTSTRAP=$GOROOT gvm install go1.5
Or even get a list of golang versions installed in your computer:
